What should come in place of x in the following equation?
x128 = 162x
Then x2 = 162x128
= Sqrt of 82 x 62 x 32
= 8 x 6 x 3
x2 = 144.
x = 12.
If (89)2 is added to the square of a number, the answer so obtained is 16202. What is the (1/26) of that number?
Let the number is = x
(89)2 + x2 = 16202
x2 = 8281
x = 91
=> (1/26) of 91 = 3.5

Find the value of 1.21x0.91.1x0.11?
Given 1.21x0.91.1x0.11
= 1.21x100x0.9x101.1x10x0.11x100
= 9
= 3.
If x = 2 + 223 + 213 then find the value of x3-6x2+6x ?
Given that x = 2+ 223 + 213
So x - 2 = 223 + 213
Now cubing on both sides, we get
=> x3-8-6x2+12x = 4 + 2 + 6(x-2)
Therefore, x3-6x2+6x = -6 + 8 = 2
If a = 5 + 15 - 1 b = 5 - 15 + 1 then find the value of a2+ab+b2a2-ab+b2 is ::
By simplifying, we get 4/3
If x = 7-43 then find the value of x+1x?
3 + 653-212-30+50 = ?
If 5+237+43 = a + b3 then a & b = ?
326-3-436-2-68-12=?
Given Exp = 326-3×6+36+3-436-2×6+26+2-622-3
= 32(6+3)6-3-43(6+2)6-2+33-2×3+23+2
= 26+3-36+2+33+2
= 12+6-18-6+33+32
= 53
